Does anyone use ventoy ?

Does anyone on the PLUG list
have experience using Ventoy?

A friend used his Ventoy USB flash
stick to install Linux Mint on a
used thinkpad t470 that I purchased.

But I then discovered that the newer
Linux Mint version that he installed
does not have many KDE capabilties
that I have always had on my older
thinkpad laptops.

So I downloaded Ventoy from
https://ventoy.net ... hoping to
install kubuntu to get those valuable
KDE capabilities that I need.

When I tried to install Ventoy, the
  system said: "Congratulations! Ventoy
has been successfully installed to the
device" ... However, the USB is blank.

So, I purchased a Ventoy USB from ebay:
https://www.ebay.com/itm/364756232958

But it came with no instructions, and
I cannot figure out how to get it to
boot on the used thinkpad t480 that I
purchased with win-10 installed.

I use Linux exclusively and have zero
experience with windblows.
